Application filed SeptemberBO, 1887. Serial No.251,i05. (No model.)

- To all whom it may concern.-

Be it known that I, JOHN L. OLsoN, of Warren, in the county of Marshall and State of Minnesota, have invented certain new and useful Improvements lin Ditching-Plows; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to ditching-plows, the object being to provide a device of this character that will be simple in construction and effective in operation.

' The invention consists in the details of construction and combinations of parts hereinafter fully described, and pointed out in the claim.

ln the drawings, Figure 1 is a view taken from the side opposite the plow. Fig. 2 is a view taken from the plow side of the machine.

Fig. 3 is a plan view, and Fig. 4 is a View taken from the rear end of the machine.

A A represent the draftwheels rigidly mounted upon the ends of the axle B.

The frame consists of the bars G C', connected together near their front and rear ends by the cross-bars C2 C3, respectively. Between the front ends of the bars C C the draft is attached, and upon the cross-bar Cifthe seat c is arranged. About midway the ends ofthe bars C C the depending arms D D are secured. The depending arms D D are perforated near their lower ends, and the axle B is passed loosely through said perforations. It will thus be seen that the frame is capable of a swinging movement in relation to the wheels and axle.

Upon the cross-bar C3, jus't to the left of the bar C, a supporting-bracket, E, is secured. The bracket E projects rearwardly at first and is then turned downwardly, the lower portion of said bracket being provided with a slot, E. The beam F is arranged between the wheels A A and adjacent to the wheel A. The forward end of the beam F is provided with the v caster-wheel j, and upon its rear end a plow,-

with a set of perforations, g, and in one of these a lever, G', is secured by passinga pin through the said lever and perforation. The lever G is pivoted upon a post, g2, and its other end is arranged to engage a set of notches, g3, in the post G2. Upon the beam F, forward of the upright G and adjacent to the axle B, a guide, H, is arranged. It will thus beseen that the height of the plow F' may be regulated so that 'itwill either make a furrow or merely pass over the surface of the ground; and it will further be seen, by reason' of the -loose joint between the beam F and the bracket E, that no matter how uneven the surface ofthe ground may be, thus causing a j olting ofthe frame and sudden rising and falling ofthe wheels,the plow will move along in a horizontal plane. v

To the outer side of the wheel A', and upon the axle B, a bevel gear-wheel, M, is secured. Depending from the bar C and cross-bar C are the braces NN,the braceNbeing arranged obliquely andthe brace N vertically.rv A shaft,

- O, is supported at its rear lend in the brace N and passes through the brace N', and its forward end isv supported in a hub, O', mounted loosely upon the end of the axle B. Near the forward end of the shaft O a bevel-gear, P, is rigidly secured, and the gear P meshes ,with the gear M. Loosely secured tov the shaft O are the side pieces, p p. The said side pieces are secured together by suitable means, and at their lower ends a roller, B,is arranged. Upon this frame and around the shaft O and roller R an endless belt or carrier, R', is adjusted. rlhe lower end of the'endless carrier is arranged adjacent to the mold-board of the plow, and is adapted to convey away the dirt thrown upon it by the plow by reason of the shaft O, provided upon itsy end with the gear P, which meshes with the gear M upon the axle B. From the foregoing it will be seen that when themachine moves, the shaft O will revolve and thus revolve the carrier B. The dirt is deposited quite a distance to the side of the ditch.

Upon the frame of the device a lever, T, is pivoted upon a post, t, and one end of said lever is connected to the lower end of the carrier S by means of the chain or other suitable v roo right G, and a guide, H, embracing the axle, and a headed pin, J, secured to the rear end of the beam and adapted to Work in a slot, E', formed in a bracket, E, substantially as described.

In testimony whereof I have signed this v specification in the presence of two subscribing witnesses.
